BEARING.

Application filed June 25, 1328. Serial No. 288,119..

This invention relates to a bearing and more particularly to a bearing seal for the front axle spindle of an automobile.

An object of the invention is to provide an axially movable bearing member between the f bearing` members of a yoke and to resihently urge the movable member in the direction of the load so that the-opposite ends of the inember between the yokeare at all tiines'in engagementwith the inner faces of the yoke bearings.

Another object of the invention is to provide a flanged bearing in the lower end of an aXle spindle, aXially movable within the spindle on the king pin. f

Other objects and advantages of the iuvention will inore fully appear from thefollowing description taken in connection with the accompanying drawings, in which:

Fig. l is a side elevation of one end of a front axle for an autoinobile,j parts being broken away, and in section.

Fig. 2 is a Sectional view of line 2e-2 of VFig. 1.

Fig. 3 is a view of a resilient member used able bearing member.

Referring to-the drawings, I have shown a portion of a front aXle 10 provided with yoke ends 12 adapted to receive and forin bearings for a king pin 14. Bushings 16 are provided in the yoke ends. In the particular form illustrated, a spindle 18 is secured to the king pin 14 between the yoke ends 12.l A steering` arm 20 is secured to the spindle to pivot' the spindle and king pin in the bearings 16.

Between the upper surface of the spindle and the lower surface of the upper yokei12, I have provided a thrust bearing 22. 'A cap 24: is positioned between the bearing 22 and the upper yoke extending downwardly enclosing the bearing 22 with its lower surface in engagement with the upper surface of the spindle. It will be understood that such a construction provides a closure for the upper portion of the bearing preventing water or dirt from entering and thereby preventing wear.

The load on the aXle is in a downward direction constantly urging the lower surface of the upper yoke toward the upper surldirt found its wear of the tween tlie lower end of the spindleand the i lower yoke resulted through which water and 1 Way to theking pin and-its bearings. f.

In the present construction, I have pro'- vided abore 26 in` the lower end of the spindle which receives a bushing 28 having a ilange 80. Between the inner end ofthe bu'shing 28 and the bottom of thebore, I have provided a resilient memberjshown as a split steel Spring washer. It will bev understood that the resilient member 32 urgesthe bashing toward the upper surface of the flower yoke landl thata seal is 'constantly 'maintained between the spindle and yoke regardless of Wear on the parts. There is pracmiV tically no weight on the bearing portion of the bushing 28 in the bore 26 which provides y a sliding fit seal between 'the bushing and the spindle.

The lower yoke opening whichv receives one end of the king pin 14 is closed by a metallie disc 34 pressed into-a bore 36. The upper end of the king pin isprovided 'with a cap 38 held in positionby a bolt 40. The cap 38 extends radially over the' upper surface of the upper .yoke and a packing 42 is provided between the cap and the yoke to sealthe upper yoke bearing against the env trance of water or dirt. It will be understoodV that by the arrangement of parts in the form of my device described7 'a construction lias been vprovidedv which is sealedat everybroken surface and that the seal is maintained regardless ofthe parts.

While I have described what I deein to be the preferred embodiment of my invention it will be obvious that various changes including the size and arrangement of parts may be made lwithout departing from the spirit of my invention and it is not my intention to limit its scope otherv than by the terms of the appended claims.

Vvhat I claim is:

1. A bearing of the class described comprising a pair of aXially aligned bearing members,` a 'pivoted member between said bearing members provided with oppo'sitely extending projections received in said bear-V ing members, a bushing slidably mounted in i one end of said pivoted memberadapted'for engagement with one of said bearing members, and resilient means between said pivoted member and said bushing.

2. A Adevice of the class described comprising, oppositely spaced bearing members, a pin supported in said bearing nembers and extending from one to the other, a pivoted member between said bearing members and carried by said pin, al member slideably mounted on said pin and partially within said pivoted member, and resilient means between said slideable member and saicl pivoted memn ber for separating said members.

3. A device of the class described comprising, a front axle shaft yoko, a king pin journaled in the yoke ends of said aide,v a spindle secured 'to said pin between said yoke ends, a

thrust bearing between the upper surface of said spindle and the adjacent bearing of the yoke, a bushing slideably mounted in the opposite end of said spindle adapted for engagement with the lower end of the yoke, and

resilient means between said bushing and said spindle. v

4. A device of the class 'described comprising, a spindle journaled in the yoke Vof an axle shaft, an annular bore in the lower end of said spindle, a. member having a portion adapted for a sliding t in said bore, and a resilient member between the base of said bore and the inner end of said member adapted to urge said member out of said bore.

5. A device of the class described comprising, a front aXle shaft yoke having axially aligned openings, a king pin journaled in said openings, a. spindle carried by said king pin, a packing carried by the upper end of .said king pin and in engagement with the upper surface of said yolre, a thrust bearing be tween the upper surface of said spindle and the lower surface of the upper yoke bearing, a cap enclosing said bearing having its opposite ends in enwagenient with the upper and lower faces of said 'spindle and said upper yoke bearing respectively, a closure for the lower surface of said yoke bearing, and means for forming a permanent seall between. the upper surface of the lower yoke bearing and the lower surface of said spindle..
